The team used SLAC's LCLS to measure atomic vibrations and ARPES to measure the energy and momentum of electrons in a material called iron selenide.

Not exact matches

«The reason for these remarkably good material properties seem to lie in a special kind of electron - electron correlation — the so - called Kondo effect,» Silke Bühler - Paschen believes.

Neutrons are ideal tools for identifying and characterizing magnetism in almost any material, because they, like electrons, exhibit a flow of magnetism called «spin.»

The range of the measurement depth can be determined by measuring a physical quantity called the inelastic mean free path (IMFP), which defines how far an electron can travel in a material while retaining its original energy level in a statistical sense.

Analysis of phase - change materials showed that they work because of a particular kind of chemical bonding, called resonant bonding — a type of bond in which electrons flip back and forth between several adjacent atoms.

In so - called Mott insulators for example, a class of materials now being intensively researched, the electrons ought to flow freely and the materials should therefore be able to conduct electricity as well as metals.

Of particular interest for modern material research in solid state physics are «strongly correlated systems,» so called for the strong interactions between the electrons in these materials.

Instead of fully eliminating the aberrations in the electron microscope, the researchers purposely added a type of aberration, called four-fold astigmatism, to collect atomic level magnetic signals from a lanthanum manganese arsenic oxide material.

In their experiments, the team observed a so - called percolation transition taking place among the electrons in the materiaIn their experiments, the team observed a so - called percolation transition taking place among the electrons in the materiain the material.

The lab of Marco Grioni at EPFL used a spectroscopy technique called ARPES (angle - resolved photoemission spectroscopy), which allows researchers to «track» electron behavior in a solid material.

The quantum behavior in this new class of materials has led them to be called «topological Dirac semi-metals» in reference to English quantum physicist and 1933 Nobel Prize winner Paul Dirac, who noted that electrons could behave like light.

The material — known as 1T» - WTe2 — bridges two flourishing fields of research: that of so - called 2 - D materials, which include monolayer materials such as graphene that behave in different ways than their thicker forms; and topological materials, in which electrons can zip around in predictable ways with next to no resistance and regardless of defects that would ordinarily impede their movement.

Inside a battery, chemical reactions involving a material called an electrolyte cause electrons to accumulate in the negative terminal, or anode, and flow when it's connected to the positive terminal, or cathode.

Instead, our current knowledge of materials is derived from a simplified perspective where electrons in solids are described in terms of special non-interacting particles, called quasiparticles, that move in the effective field created by charged entities called ions and electrons.

In the experiments, researchers used a technique called angle - resolved photoemission spectroscopy, or ARPES, to knock electrons out of a copper oxide material, one of a handful of materials that superconduct at relatively high temperatures — although they still have to be chilled to at least minus 135 degrees Celsius.

The vibrations are called phonons, and the electron - phonon coupling the researchers measured was 10 times stronger than theory had predicted — making it strong enough to potentially play a role in unconventional superconductivity, which allows materials to conduct electricity with no loss at unexpectedly high temperatures.

CALIPSOplus is an Integrating Activity for Advanced Communities in reply to the call INFRAIA -01-2016 (Material Sciences and Analytical facilities / Synchrotron radiation sources and Free Electron Lasers) in Horizon2020 the European Framework Program for Research and Innovation.
